Amazon is still refining its checkout-free grocery experience, Amazon Go, but there are new signs that the online retail giant is eyeing expansion of the concept.

In May, Amazon posted a job for a senior real estate manager for Amazon Go. Some of the duties included in the posting, first spotted by The Seattle Times, are site selection, working with local brokers, negotiating leases for new locations and putting together a strategic real estate plan for Amazon Go.

The posting suggests that there could be future Amazon Go stores outside of the company’s hometown as the position is based in Seattle but includes travel.

Amazon officials did not immediately respond to a request for comment.

The first Amazon Go store was unveiled late last year with an announced opening to the public in early 2017 2017. Amazon reportedly delayed the opening of the first store in order to fix issues with the customer tracking technology that enables the store to function without checkout lines.

Despite these setbacks, it appears Amazon may be moving ahead with international expansion of the Amazon Go concept. United Kingdom’s Intellectual Property Office last month signed off on Amazon applications to trademark multiple slogans associated with Amazon Go. A similar application is being reviewed by equivalent organizations in the European Union, and, Amazon also trademarked the Amazon Go logo in the U.K. late last year.
